Al-Qaeda, which has announced the creation of a separate wing for India, wants to portray Prime Minister Narendra Modi as an enemy of Islam and as such India should take its threat "very seriously", a well-known American counter-terror expert said today even as the US tried to downplay the terrorist outfit's capabilities.

"This video, the first from (al-Qaeda leader Ayman Al-) Zawahiri this year, should be taken very seriously. Al-Qaeda wants to portray Prime Minister Modi as an enemy of Islam," ex-CIA analyst Bruce Riedel, who is considered to be one of the US' top experts on counter-terrorism, said.

At the same time, she reiterated that the US remains committed to dismantling al-Qaeda anywhere that it poses a threat to the US and make sure that it doesn't renew its threat to America.

But many counter-terror experts like Riedel do not necessarily agree with the State Department and view this as a new threat from al-Qaeda.
